Multiple regression is a method to build a model described by more than one variable. In many cases, the model you are interested in is linear, so you can think this as an extension of [[HCIstats:​LinearRegression|linear regression]]. But you can include non-linear terms if you want to. In this page, I only explain the procedure of linear multiple regression, but the procedure of the non-linear version is basically the same (well, if you have a term of the multiplication of two factors, things become different. For more details, see the Interaction section of this page).
